Transcript termination is essential for accurate gene expression and the removal of RNA
polymerase (RNAP) at the ends of transcription units. In bacteria, two mechanisms are …

The process of transcription termination is essential to proper expression of bacterial genes
and, in many cases, to the regulation of bacterial gene expression. Two types of bacterial …

Rho is a ring-shaped hexameric ATP-dependent molecular motor. Together with the
transcription elongation factor NusG, Rho mediates factor-dependent transcription …

Bacterial conjugation results in the transfer of DNA of either plasmid or chromosomal origin
between microorganisms. Transfer begins at a defined point in the DNA sequence, usually …

The study of the biosynthetic pathway leading to synthesis of the amino acid histidine in
prokaryotes and lower eukaryotes was begun more than 40 years ago (119) and has …

Genes on an 8 kb region common to the virulence plasmids of several serovars of
Salmonella are sufficient to replace the entire plasmid in enabling systemic infection in …

In bacteria, one of the major transcriptional termination mechanisms requires a RNA/DNA
helicase known as the Rho factor. We have determined two structures of Rho complexed …

The transcription termination factor Rho is a global regulator of RNA polymerase (RNAP).
Although individual Rho-dependent terminators have been studied extensively, less is …

Transcription factor Rho is a ring-shaped, homohexameric protein that causes transcript
termination through actions on nascent RNAs that are coupled to ATP hydrolysis. The Rho …

Rho-dependent transcription terminators participate in sophisticated genetic regulatory
mechanisms, in both bacteria and phages; they occur in regulatory regions preceding the …
